Four earthquakes ripple through Valley Monday

POLAND TWP., Ohio - Four earthquakes shook parts of the valley Monday morning. All of the tremors were centered in Poland Township.
The Lamont-Doherty Cooperative Seismographic Network reports a 3.0 magnitude earthquake close to 2:30 a.m. Monday, just east of the Poland Township Park.
A second tremor, a 2.4 magnitude, was recorded 16 minutes later on the west side of the park.
Shortly after 11 a.m., a third 2.2 magnitude earthquake was registered north of Cowden Road in the area of the Carbon Limestone Landfill.
About forty minutes later, the center of a 2.6 magnitude quake was reported close to the last tremor.
The 3.0 magnitude earthquake was strong enough to wake up some homeowners in Poland Township early Monday morning.
One Poland resident tells 21 News that he was awake at home when the 3.0 earthquake rattled his house.
